Hmm I thought I had to do some special handlings for Expression.NIL to cater
for polymorphism. Didn't think it'd work for normal sourceExpression, I
can't remember what I did but maybe it was already working.. anyway that's
good :D. I used Expression.NIL because the ECQL parser in app-schema can't
This works- the property is omitted for the appropriate cases. An
internet search for _expression_.Nil turned up this link:
http://docs.geoserver.org/trunk/en/user/data/app-schema/polymorphism.html#null-or-missing-value
with example:
if_then_else(isNull(VALUE), _expression_.NIL, 'gsml:CGI_
Try:
if_then_else(equalTo(CAT_DESC, 'No Name'), Expression.Nil,
CAT_DESC)
I found this in Rini's polymorphism.xml (used in PolymorphismWfsTest, in
the feature with id=f4) but I have no idea how she found it! If it
works, we should document it.
xs:nillable means that an element with a non-empt
Thanks for all these links. I have almost managed to get the syntax I
am looking for. I am still stuck on setting a field to NULL.
This _expression_ parses
if_then_else(equalTo(CAT_DESC, 'No Name'), 'NULL',
CAT_DESC)
This does not
if_then_else(equalTo(CAT_DESC, 'No Name'), NULL,
CAT_DESC)

I have been attempting to use ECQL expressions in an app-schema mapping
file, but am having trouble with the syntax.
The link given in the Geoserver manual
http://udig.refractions.net/confluence/display/EN/Common+Query+Language
is broken.
The only ECQL reference I have been able to find is
